ADJUSTABLE LAND-s ns ATTAGHMENT FOR ROAD enAnERs.

Application filed February 28, 1923.- SeriaIVNo. 621,817.

To all whom it may concern: 7

Be it known that I, ATHUL A. FULOHER,

a citizen of the United States, .residin at Kinta, in the county of- Haskell and tate of Oklahoma, have invented certain new draft on the tractor means carrying the grader element.

A further object of the invention is to provide in a manner as hereinafter referred to, a landside attachment forthe purpose set forth,:having means for adjusting the same relativelyto the position ofthe grader element for the purpose of holding thelatter during its operation in position to cause the grading of an even ditch;

Further objects of the invention are to provide an adjustable landside attachment for road graders, which is simple in its construction and arrangement, strong, compact, durable, readily setup with respect to the grader element, thoroughly'eflicient in its use, conveniently .adjusted .when occasion requires, and comparatively inexpens1ve.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and-illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and. modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several vie-ws:

the means for connecting the sections of the adjustable coupling bar together. Figure 10 is a fragmentary view, partly in section, of the adjustable coupling bar.

Figure 11' is a detail of one of the elements of the securing or holding means Ifor the sections of the adjustablecoupling Referring to the drawings in detail, the grader element comprises a moldboard l and a scraping or cutting blade 2. The moldboard 1 is segment shaped in vertical .section, and theblade 2 conforms to the shape of the moldboard 1. The blade 2 is detachably connected with the moldboard 1,

by the hold-fast devices 3, and the blade 2- is positioned in suchmanner with respect to the moldboard 1, that the blade will proj ect beyond the lower edge thereof, as clearly shownin Figures 2 and 4. The operative position of the grading element is at an inclination and is supported in such position from a traction means, not shown.

As is well known, when grading, unless a means is provided for the grader element to arrest shifting laterally with respect to the line of the ditch. that the blade will cut "into the bank at one side of the ditch at soft places, thereby stalling the traction means and making a very uneven ditch as well as causing a heavy side draft onthe traction means as is obvious, and to prevent this lateral shifting or penetration of the Figure 9 is a sectional detail illustrating blade. into soft, places of the bank, the

grader element must be provided with a landside attachment which moves against the bank and holds the grader element in a position at all times to provide for the l n ng p of th dit h or road in an even manner, or on a substantial perfect. line, and the landside attachment in accordance with this invention comprises a landside element and an adjustable coupling bar 7 member 4 and of a length as to-project beyond the forward end of said member 4. Hold-fast devices 6 are employed for detachably connecting the bar 5 to the body portion 4,

The forward end of the body portion 4 is bent inwardly at a slight inclination and enlarged as indicated at 6, and the said enlargement 7 is provided with a vertically disposed opening 8. The enlarged forward end of the member 4 is of a length less than the width of said member 4 and is so arranged that the top of the enlarged end 7 will be positioned below the top edge of the member 4 and the bottom of the enlarged end 7 will be positioned abovethe lower ed e of'the member 4.

Ee'cured to the rear face of the moldboard 1, in proximity to one end thereof, is an angle shaped member formed of an arm 9, and an arm 10. The arm 9 is secured in any suitable manner to the rear face of the moldboard 1, and the arm 10 projects rearwardly therefrom and; is bifurcated. The furcations of the arm 10 are indicated at 11, and each of which is provided with an aperture alignin with the opening 8. The enlarged end of the member 4 is positioned between the furcations 11, and extending through these latter, as well as the enlarged end 7, is a bolt 12, provided on its lower end with a holding nut 13; The enlarged end 7 of the member 4, fnrcations 11, and bolt 12 hinge the forward end of the landside element with the grader element.

The landside element when set up in op erative position with respect to the grader element extends rearwardly at right angles with respect to that end. of the grader'element to which the landside element is hinged.

The'land bar 5, of the landside element has its forward endextended to oppose the outer face of the arm 10, as clearly shown in Figure 5.

The adjustable coupling bar which is employed for adjusting the position of the landside element with respect to the grader element, is not only hinged with the landside element but also hinged to the grader element and is furthermore adjustable lengthwise to the desired extent to properly position the landside element with respect to the grader element The adjustable con- 16 of the section 14.

pling bar is formed; of two sections 14 and 15, the latter interfitting with the former and is of less width than the section 14. Each of the sections 14, 15, is rectangular in contour and of substantiallength. The outer end of the section 14 is enlarged as at 16, and extended slightly at an angle with respect to the remaining portion of the section 14, and said enlar ed; end is provided with an opening 17. ecured to the inner face of the member 4, near the rear end thereof, by the hold-fast devices 18, isa plate 19, provided with a bifurcated portion 20 into which extends the enlarged end The furcations formed by the bifurcated end 20, of the plate 19, are indicated at 21, and which overlap the enlarged end 16 of the, section 14. Extending through the fnrcations 21 and the opening 17 is a bolt 22, provided on its lower end with a securing nut 23. The enlarged end 16, of the section 14, in connection with the furcations 21 and bolt 22, sets up a hinged connection between the outer end of the section 14 and the rear end of the landside element. 7

The rear end of the section 14 has secured to the inner face thereof a channel shaped member 24, and the securingmeans for the member 24 is indicated at 25. The member-24 in connection with the section 14 provides a passage 26 for the section 15, as well as constituting means for connecting the section 15, in sliding engagement with the section 14. The member 24 is formed with an opening 27, which aligns with an opening 28, provided in the section 15, and; the openings 27, 28, are adapted to register with an opening 29, of a series of openings formed in the section 15.

Fixedly secured to the rear end of the section 14, at the outer face thereof, by the hold-fast devices 30, is a yoke 31, formed with an opening 32. which aligns with the openings 27, 28. Extending through the openings 32, 27, 28 and that opening 29 which registers with the openings 27 and 28, is a spring controlled retaining member 33, in the form of a short cylindrical rod, and its function is to retain the sections 14 and 15 in adjusted position. The retaining member .33 projects outwardly from the yoke 31, and carries on its outer end a head piece 34 to provide for the convenient manipula tion of said member 33. Extending through, as well as being secured to the member 33, at a point between its center and its inner end, is a pin. 35, which projects laterally at each end from the member 33. The pin 35 engageswith the section 14 and limitsinward movement of the member 33. Mount ed on the member 33 is a retaining plate 36, formed with an opening 37 for the passage of the member 33, and further provided on its inner face with a pair of oppositely extending grooves 38 which provide seats for the projecting ends of the pin 35. The length of the plate 36- is slightly less than the distance from one of the legs to the other of the legs of the yoke 31, and said plate 36 is prevented from turning on the member '33 by the engagement of the pin 35 in the and from shifting relatively to each other.

The pressure of the spring 39 against the plate 36, and the latter bearing against the ends of the pin 35 will maintain the member 33 in the position as shown in Figures 8 and 9. When the member 33 is pulled outwardly, such action is had against the tension of the spring 39, and when the member 34 is released, the spring 39, owing to its action on the plate 36, will shift the mem ber 33 to holding position.

For the purpose of maintaining the mem ber 33 stationary, when pulled outwardly, to enable the convenient adjusting of the sections 14, 15, the yoke 31, is provided with a pair of oppositely disposed and inwardly extending lugs 40. The width of the plate 36 is such that it can pass between the lugs when the member 33 is pulled outwardly and after the latter has been shifted outwardly to the extent to carry the plate 36 to a position outwardly with respect to the lugs 40, the member 33 is then given a quarter turn and released, whereby the spring 39 will force the plate 36 against the lugs 40 and the member 33 will be held from shifting inwardly until the plate 36 is moved to a position so that it can slide inwardly between the lugs 10. When the member 33 is pulled outwardly the pin 35 is carried therewith, and the latter has its projecting ends arranged outwardly of the lugs 40 in the same manner as the plate 36.

The outer end of the section 15 extends through the passage 26 and the inner end of the section 15, is hinged to the rear of the moldboard 1, as at 41.

The hinged connection between the landside element and the grader element, as well as the hinged connection between the adjustable coupling bar and the grader element and between the adjustable coupling bar and the landside element provides means whereby the landside element can be shifted to the desired position with respect to the grader element when the length of the coupling bar is increased or diminished, and by this arrangement the landside element can always be positioned to extend at right angles in a rearward direction with respect to one end of the grader element so that the latter will be prevented from penetrating in the bank to a distance which Would cause uneven ditching, or stalling the tractor means, or setting up a heavy side draft on the tractor means, and although the preferred embodiment of the invention is as described and illustrated, yet it is to be understood that changes in the details of construction can be had which will fall within the light of the invention as claimed.

What I claim is In combination, a mold board having a lengthwise extending blade depending therefrom, a rearwardly extending right angularly disposed arm projecting from the rear face of said board at one end thereof, said arm having its rear end bifurcated, a rearwardly extending rectangular member having a reduced forward end extended between the furcations of said arm and pivotally connected therewith, said member arranged throughout above the bottom of said board, a land bar positioned against the outer face of said member and having its forward end projecting beyond the forward end of the member and further opposing one end of said board, means for detachably connecting said land bar to the outer face of said memher, a plate positioned against the inner face of said member in proximity to its rear end and formed with a bifurcated rear end, means for securing said plate to the rear of said member, a permanently inclined lengthwise adjustable sectional coupling bar positioned between said board and member, means for hinging one end of said bar to the bifurcated end of said plate, means for hinging the other end of said bar to the rear face of said board at a point intermediate the ends thereof, and means permanently carried by said coupling bar for securing it in its adjusted position.

In testimony whereof, I affix my signature hereto.
